**Method:3 **
Let us learn arranging the given series of numbers 5,1,3 in ascending order. i.e. from least to greatest.

**Step 1:**
Write down the given numbers.

**Step 2:**
The first smallest number is 1. So, 1 comes first in the order.

**Step 3:**
The next number is 2. But, it is not present in the given series 5, 1, 3. So, omit "2"

**Step 4:**
3 is the next largest number, and it is present in the given order 5, 1, 3. So, include "3".

**Step 5:**
The next largest number is 4, and it is not present in the given order 5, 1, 3. So, omit "4".

**Step 6:**
5 is the next largest number and "5" is present in the given order 5, 1, 3. So, include "5".

Now, arranging in ascending order (from least to greatest) i.e,

**i.e.**

If you want to arrange numbers in ascending order, then you should always pick the smallest number first.
